Wristlet here too, or jeans pocket (front), or heck, just in my hand. Husband carries his in whatever pocket it fits in that day, jeans, cargo pants, various jackets. Both of us have the iPhone 6. He uses a folio wallet style case, I use a super slim one that's basically only useful for adding a bit of grip.
We're treating them about the same as we did the 5, 4, and original iPhones we had, and they seem to be fine.
